An unidentified woman did something truly remarkable for a father and his 2-year-old daughter when they realized that the toddler was not allowed to fly for free after the agent asked for her age.

According to the contributor, "(the father) said she had recently turned two. The agent then asked if she had a ticket. The man was confused because he was under the impression she could ride for free. (When he booked the ticket, she was one but her birthday was in January.) He was hit with emotion. He mentioned he couldn't afford to rebook this flight or get her the ticket with such short notice. He stepped aside and tried to make a few calls. Hugging his daughter and grabbing his head, you could tell he was heartbroken. This woman next to him at the front counter heard the whole thing. She walked over to him and asked what was wrong. After they talked for a bit they walked up to the counter together. "

That's when the woman did something completely startling: she gestured to the 2-year-old and said, "I want to buy her ticket." The agent mentioned the price – $749 – but the woman held fast, putting the charge on her credit card.

As the man hugged and thanked her in front of the amazed ticket agents, he asked for her name and address so her could pay her back. "Don't worry about it," she said.

She did something absolutely selfless for a stranger with no hope of repayment or recollection at a time when someone needed it most.

One commenter claimed to the know the stranger, but offered no identifying details, instead preferring to tell a little bit about her and how she lives her life. These comments, if true, explain so much about her actions.

This woman's example can inspire us all, and that doesn't mean having to put down a credit card every time someone in front of you can't afford something.

It's less about the action itself than the attitude: to do what is needed without being asked. It doesn't cost anything to stop and check on someone who looks like they could use a hand, even if it's just asking if they're OK. Standing for someone on a crowded train doesn't require a huge balance in your bank account. Comforting a child? That's also free. Walking someone back to their dorm late at night? Requires nothing but time.

You already know what needs to be done. Do what you can, when you can... simply because you can.
